SOMERSET, Pa. — The ex-wife of a Western Pennsylvania man authorities said was killed in 2008 is now charged with murder, and her son — who was charged earlier — now says that his mother killed the victim and has led authorities to a body.

Jeanette Battle, 62, of Reading, is charged in Somerset County with criminal homicide, aggravated assault, conspiracy, arson, reckless endangering, evidence tampering and weapons counts, among other charges.

Battle’s son, Samuel McFarland Jr., 38, was charged last month with killing 56-year-old Thomas Conrad after police and prosecutors said he had bragged about killing the victim, then burying the body in a remote area.

But prosecutors said Saturday that McFarland told them earlier this month that Battle had actually been the one who killed Conrad. He said the two then buried the body and Battle later set fire to their home.

Authorities say he led them to a spot in the southern part of the county near a strip mine where, after several searches, a body was uncovered and taken to Mercyhurst University for forensic analysis.

District Attorney Lisa Lazzari-Strasiser said at a news conference Saturday that she didn’t think charges would have been filed without a body, The (Somerset) Daily American reported. She said it was unlikely that the body wasn’t that of Conrad, but police sent it for examination to be sure.

Court records don’t list an attorney for Battle; a listed number for her couldn’t be found Saturday.
